Abstract

A semi-conductive magnetic flux sensor is disclosed in which semi-conductive material having a resistance on the order of at least 500 ohms per square is placed in a lateral electric field of at least 500 volts per centimeter. A signal probe or contact located between the two lateral field contacts produces an output voltage when the sensor is subjected to magnetic fields having at least some component perpendicular to the plane of the three contacts. The device is highly sensitive and yields approximately one order of magnitude higher signal output than conventional Hall type semi-conductive magnetic sensors.
